SHIRT-STUD FASTENER.

SPECIFICATION forming part of Letters Iatent No. 546,989, dated October1, 1895.

Application filed February 895- Serial No. (N0 model.)

To all whom it may concern.

Be it known that I, HENRY H. BAKER, Jr., a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and useful Improvement in ShirtStud Fasteners, of whichthe following is a specification.

This invention relates to a fastener for preventing a shirt-stud frombecoming accidentally detached and from being unscrewed from the outerside of the shirt-bosom.

My invention has for its object to provide a simple and inexpensivedevice of this character which is readily applied and removed and whichreliably retains the stud in place, and at the same time serves as ahood or guard whereby the point of the spiral stud-shank is preventedfrom catching in the underwear or chafing the wearer.

In the accompanying drawings, Figure l is a sectional elevation of myimproved fastener applied to a stud. Fig. 2 is a detached sectional viewof the fastener, showing its slotted lid open. Fig. 3 is a cross-sectionthereof in line 3 3, Fig. 1. Fig. at is a top plan view of the fastenerwith the slotted lid closed. Fig. 5 is a sectional elevation of amodified construction of the fastener.

Like letters of reference refer to like parts in the several figures.

A is the shirt-stud, having the usual wire screw or spiral shank b, andO is a portion of a shirt-bosom having the usual opening for the passageof the spiral shank.

D is a shallow box or case, preferably of cylindrical form, which formsthe body of the fastener and which receives the spiral shank. The bottomof this case is closed,so as to present a smooth surface to the undergarment and keep the spiral shank out of contact therewith.

E is a lid or movable plate, which closes the open front end of thecase, and which is preferably hinged to the case at one edge andprovided at its opposite edge with a spring catch or lip e, whichengages over a projecting rim formed at the adjacent edge of the case,so as to hold the lid in its closed position and at the same time permitit to be opened easily.

The lid E is provided with a radial slot 6, which extends from the edgeof the lid to the middle thereof, and which receives the neck of thespiral shank preparatory to closing the lid. the neck of the spiralshank freely, and its inner end preferably terminates in a circularaperture or enlargement 6 through which said neck passes.

fis a stopfpin, or projection, which is arranged in the case D in thepath of the radial portion 1) of the spiral stud-shank, and whereby thecase and the lid are compelled to turn backward with the shank, thusdefeating any attempt to unscrew the stud from the outer sideof theshirt. The stop-pinfis preferably arranged to register with the innerportion of the slot in the lid, so as to occupy and obstruct the innerend of the slot when the lid is closed, as shown in Fig. 4. In case thefastener should be used in connection with a smaller spiral than thesize for which it is intended, the radial portion or first convolutionof the spiral is by this relative arrangement of the stop and the slotin the lid prevented from entering or protruding through theinnerportion of the slot and permitting the spiral to be started andunscrewed from the fastener. In order to further check the passage ofthe radial portion of the spiral shank through the slot of the lid, thestoppin is formed at its free end with a head, as shown.

In applying the fastener to the stud the lid is opened and its slot ispassed over the neck of the spiral stud-shank until the neck enters theenlargement at the inner end of the slot, and the case is then closedover the spiral and interlocked with the catch of the lid, therebyconfining the lid between the back of the shirt-bosom and the front endof the spiral shank and retaining the fastener on the shank. If asurreptitious attempt should be made to unscrew the stud, the radialportion of the spiral shank will strike the stop-pin f and compel thecase and lid to turn with the shank, thus efiectually preventing theshank from turning backward independently of the fastener and renderingit impossible to start This slot is just wide enough to receive theshank. The case completely incloses the shank, and the point of thelatter cannot, therefore, penetrate the underwear and chafe or scratchthe wearer, as it does when unprotected.

The wearer can readily detach the stud after removing the shirt bydisengaging the catch of the lid from the case, swinging the case clearof the spiral shank, and stripping the slotted lid from the neck of theshank.

Instead of arranging the stopf on the bottom of the case, it may belocated on the inner side of the lid, as shown in Fig. 5, so as to standin the path of the radial portion of the spiral when the lid is closed.In this case the stop is preferably arranged at one edge of the slot andnear the middle thereof, as shown.

I claim as my invention 1. A shirt stud fastener, comprising a caseadapted to receive the shank of a stud, a lid or removable plate closingthe open end of said case and having a slot extending inward from itsedge, and a stop or projection arranged in the path of the radialportion of the stud shank, whereby the fastener is compelled to turnwith the stud, substantially as set forth.

2. A shirt stud fastener, comprising a case adapted to receive thespiral shank of the stud, a lid or movable plate closing the open end ofsaid case and having a slot extending inward from its edge, and astop-pin projecting from the bottom of said case and arranged to enterthe slot of the lid when the latter is closed, whereby the pin obstructsthe slot, substantially as set forth.

3. A shirt stud fastener, comprising a case adapted to receive thespiral shank of a stud, a hinged lid applied to the open end of saidcase and having a radial slot extending inward from its edge, and astop-pin projecting from the bottom of the case and having a head whichobstructs said slot when the lid is closed, substantially as set forth.

Witness my hand this 1st day of February, 1895.
